Troubleshooting on Macintosh

Installation difficulties

If you are unable to copy the Mathematica CalcCenter application to your hard drive, you may not have write privileges to the destination folder. Copy the application to another location, such as your home folder, or log on as administrator.
If problems persist or for late-breaking news, check the technical FAQs for your platform at


When you installed Mathematica CalcCenter, you probably noticed that there was a single icon rather than a folder full of other folders, as was the case with applications on Mac OS 9 and earlier. This is because the Mac OS X icon is both an application and a folder.

You can double-click the icon in the Finder to launch Mathematica CalcCenter, just like a normal application. If you ControlKeyKeyBarclick the icon, a pop-up menu appears that allows you to show the contents of the bundle, revealing the folder structure underneath. Apple usually calls these packages; however, to avoid confusion with other Wolfram Research application packages, they are called bundles in this guide.

Optimizing available memory

To reduce Mathematica CalcCenter's memory usage:

  • Bullet Close notebooks when you are finished with them.
    Bullet Clear the Clipboard by copying something small to replace large data.
    Bullet Set your monitor to fewer colors using the Monitors control panel.
    Bullet Save notebooks after large results and plots.
  • Window title bars

    When you make changes to a file, the red Close button changes to indicate that the file has been changed since the file was last saved.


    Pathnames now use a POSIX-style forward slash instead of the older Macintosh colon. The root of the system is designated by / on Mac OS X, and the current directory on Mac OS X is . (a period).

    Preferences and Caches

    Mathematica CalcCenter preferences, such as the names of recent palettes and style sheets or the locations of recently opened and saved files, are stored in an initialization file called init.m. This file is located in the directory ~/Library/MathematicaCalcCenter/FrontEnd.

    Information about your layout, such as the locations of text resource files and Help Browser files, is stored in caches. A corrupted cache may cause the front end to produce an error or quit immediately on startup. The most convenient way to reset the caches to their default values is to hold down ShiftKeyKeyBarOptionKey during startup. This will restore the default cache values and rebuild the initialization file automatically.

    To reset your caches and preferences:

  • 1. Hold down ShiftKeyKeyBarOptionKey during startup. Mathematica CalcCenter will start up, but no controllers will appear.
  • 2. Quit Mathematica CalcCenter.
  • 3. Restart Mathematica CalcCenter without holding down ShiftKeyKeyBarOptionKey. This will restore the default cache values and rebuild the initialization file automatically.
  • If you want to rebuild your caches but retain your preferences, follow these steps, but hold down only ShiftKey in step 1. This will delete and rebuild the cache without rebuilding your initialization file.


    Bitmap caches are created for graphics to allow for quick retrieval of images. If you change the settings in /Applications/System/Preferences/Display, graphics may appear strange. To rerender a graphic, resize it by selecting the graphic and dragging a graphic handle.

    File extensions

    Mac OS X can work with several different file systems, including HFS/HFS+ (the native Macintosh file system), Unix file system (UFS), and Network File System (NFS).

    If you save a file on a non-HFS/HFS+ volume, you must name the file with a .nb extension to have Mathematica CalcCenter launch when you double-click the file's icon. On an HFS or HFS+ volume, the extension is optional.


    Several Mathematica CalcCenter fonts are installed in the bundle. After you run Mathematica CalcCenter for the first time, the fonts will be available to any program on your system. You do not need to know which font a particular character is from in order to use it; this is handled automatically by Mathematica CalcCenter.
